How many colonies did you pick to screen? Even with the worst of luck
(which it seems you may be having; did you do the ritual, obligatory
cloning dance to the Molecular Biology Gods before you started :-)), if I
pick twelve colonies (i.e., one microfuge rotor's worth), I can get my
orientation in at least 1 colony. Actually, to date, my worst luck has
been 3/12 correct orientation.
To answer the other part of your original question: Never heard of
"directional preference" with identical sites.
